MACHINERY FOR SHAPING, FINISHING, AND FLANGING METAL BARRELS, 8L0.

SPECIFICATION forming part of Letters Patent No. 470,737, dated March 15, 1892. Application filed May 1] 1891. Eterial No. 392.253. (No modeli) To all whom it may concern.-

Be it known that I, THOMAS CRITOHLEY BARRACLOUGH, of London, England, haveinvented certain new and useful Improvements in Machinery for Shaping, Finishing, and Flanging Metal Bodies for Barrels and other Similar Vessels, of which the following is a specification.

My invent-ion has reference to machinery for shaping, finishing, and flanging metal bodies for barrels and other similar vessels, and more particularly when such bodies have internal ribs and have been part formed from a hollow ingot or weldless or a welded tube by rolling on a mandrel-and then subsequently expanding into approximately the diameter of a barrel-body. A machine for effecting this expanding operation forms the subject of another application for patent filed May 11, 1891, Serial No. 392,254.

The improvements consist in the combination, with a roller upon which the barrel-body to be operated upon is placed and which has a contour corresponding with that required in the finished body, of a fulling-roller having a reciprocating longitudinal traversing motion for acting upon the barrel-body and imparting to it a contour corresponding with that of the roller which carries it.

The improvements further consist in the combination, with the said roller upon which the barrel-body is placed and with the said fulling-roller, of guide-rollers for the purpose of maintaining the circular shape of the barrel-body.

The improvements also consist in the combination, with the said roller upon which the barrel-body is placed and with the said fulling-roller, of finishing-rollers for removing any roughness or unevenness left on the barrel-body after the action thereon of the fulling-roller.

The improvements also consist in the combination, with the said roller upon which the barrel-body is placed, of apparatus for giving an outwardly-turned flange to each end of the body.

The invention further comprises. various subsidiary combinations and improvements, which will be fully understood by the description hereinafter given.

In the accompanying drawings, Figure 1 is a plan of a machine in which my improvements are embodied. Fig. 2 is a side elevation; Fig. 3, an end elevation, partly sectional; Fig. 4, a detail view showing in elevation the flanging-rollers B B, conical rollers E 'E, and roller a.

I will first describe the shaping and finishishing portion of the machine and then the flanging apparatus.

C6 is a roller, which is shown as convex to correspond with the required swell or belly on the barrel-body; but if the body is to be cylindrical the roller Ct will also be cylindrical. The said roller is shown with circular grooves a for the purpose of. completing the formation of a corresponding number of internal ribs in the barrel-body when it has been previously formed with such ribs; but if the barrel-body is plain the grooves a in roller a will be dispensed with. It is driven by any suitable engine, the motion from which is transmitted to the toothed wheel a on the roller-shaft.

fis a cap fitting over one of the necks or journals of the roller a, and this cap is raised by hydraulic power to enable the barrelbody to be placed upon, and when finished.

removed from the said roller, and the same power gives the necessary downward pressure when the roller is caused to rotate for the purpose of rolling the barrel-body. The bydraulic power is applied by means of a hydraulic cylinder b with piston, the rod 0 of which is cottered on across-rail d, from which rise two vertical rods 6 e, to which the cap f is attached; It will readily be understood that when downward pressure is required for rolling a barrel-body it is obtained byadmit ting water into the top of the cylinder b,-and

that when the barrel-body is finished and has to be removed from the machine the valves of cylinder 12 are reversed, water beingthus admitted to the bottom of cylinder b, so that the cap f is forced up and the barrel-bodycan be removed.

g is a fulling-roller attached to a carriage h,

which receives a reciprocating longitudinal traversing motion through the intermediation of rods '5 c and a cross-head (not shown) from the rod of a piston working in a hydraulic cylinderj. This fulling-roller begins to act at the middle of the barrel-body and the hydraulic piston in j has a gradually-increasing stroke imparted to it until the full length of the barrel-body has been traversed. The f n11- ing-roller carriage h is kept concentric with the convex roller a by means of a copy or templet It, having the same curve or radius, and it is guided during its traverse byslides Z. The fulling-roller g can be adjusted in a direction at right angles to the axis of the barrel-body by means of the screw m and capstan-nut n. This nut is attached to the carriage h and enables this carriage to be raised and lowered, as required.

In order that while the fulling-roller g is at work the barrel-body, which is of larger diameter than the convex roller a, may maintain its circular shape the machine is provided with guide-rollers o 0. These are carried on a bracket 1), fixed to a cross-rail q, the whole being adjustable by means of the screws r a", which are actuated simultaneously by the worm-shaft t and worm-wheels s 5, being under the control of the attendant, a key or hand-wheel being fitted for the purpose on the end of the said shaft. hen the fulling-roller has completed its operations, the outer surface of the barrel-bodywill be more or less rough in the form of a series of faint grooves. To remove this roughness and give a smooth and even finish to the barrel-body, the machine is provided with finishing-rollers to u, having their surfaces shaped to correspond with the surface or contour of the roller a. They are kept in contact with the barrel-body by the piston-rods of hydraulic cylinders 'u, and can be moved away from the said body when required by admitting water to the opposite end of the said cylinders.

I will now describe the flanging apparatus to which the barrel-body is submitted after having been shaped and finished, as already explained. This flanging apparatus is duplieated, so as to act on the two ends of the body, and is fitted on that side of the machine where the finishing-rollers a a are situated. \Vhen the flanging apparatus is required to be put into operation, the rollers u a are withdrawn from their working position byadmitting water to the upper end of the hydraulic cylinders 'u. The flanging apparatus is carried on the cross-rail A and is composed of V-grooved rollers l3 B, in conjunction with which are conical rollers E E for forming a sharp corner underneath the flange when this is completed. The rollers I) Bare mounted on studs K K and actuated radially by hand-wheels L L, Worm-shafts M M, and worm-sectorsN N, all of which are carried on brackets or frames 0 O.

Adjustment of the apparatus in the direction which is parallel to the axis of the barrel-body is obtained by means of the bolts F F, which when their nuts are slacked are free to be slid along slots G G in the rail A. Adjustment in the direction which is at right angles to the axis of the barrel-body is obtained by means of the dovetail slides H H,

which can be moved forward or backward by means of the screws J J and hand-wheels I I.

The guide-rollers 0 0 (already described) are set up to the extent necessary to force the barrel-body against the convex roller a, the barrel-body being thus made to revolve. As soon as it begins to revolve, other guide-rollers D D on the opposite side are set up until they touch it. After this the V-grooved rollers B B are brought into action by the attendant by means of the hand-wheels L L, wormshafts M M, and sectors N N, and the ends of the barrebbody, which is indicated at X in Fig. 1, are thereby bent over and pressed against the conical rollers E E, the required flange at each end being thus formed.

The machine should be provided with suitable apparatussuch, for example, as a series of jets burning a mixture of gas and air supplied under pressurefor heating the barrelbodies during the shaping, finishing, and fianging process.

Instead of employing hydraulic power for bringing the necessary downward pressure upon or for lifting the cap f and for moving the finishing-rollers u a into and out of their working position, it is obvious that other power-such, for example, as sciew-powercan be employed; also, that steam or other fluid pressure can be substituted for hydraulic pressure for imparting the reciprocating motion to the fulling-rolle'r carriage h.
